Hello!

I wanna ask you guys for help with this program. Here is my problem explanation: I want that user gives an input in the beginning of the program how big should tictactoe board would be. For example: input: 4 so board would be 4x4.

Code of the current problem is:

#include <iostream>

using namespace std;

int main(){
    //These variables are holding the value of each square (0 = free, 1 = x, 2 = o)
    int one = 0;
    int two = 0;
    int three = 0;
    int four = 0;
    int five = 0;
    int six = 0;
    int seven = 0;
    int eight = 0;
    int nine = 0;
    //This holds the number of the current player (1 = player1(x), 2 = player2(o)
    int turn = 1;
    //These variables are holding the row and column number inputted by a player
    int row;
    int column;
    //These variables will be used later to check if a move is valid or not
    bool validmove;
    bool validrow;
    bool validcolumn;
    //The bellow variable holds the number of the winner, when the value is not 0 means the game is over
    int winner = 0;
    //The game loops again and again until somebody wins or it`s tie (winner = 3)
    while(winner == 0){
        //Draw the board from simple +,- and | characters
        cout << "1 2 3" << endl << "+---+---+---+" << endl << "1 | ";
        if(one == 0){
            //For each square the variable of that square is checked, and based on it`s value a character is written (0 - nothing, 1 = x, 2 = o)
            cout << "|";
        }
        else if(one == 1){

Thanks for the help in advance.

You need a dynamic array or a vector to do this in a non-ghetto way. Do you know how to use those?

Sorry I don't :( If you could help me, I would really appreciate it! Thanks for reply.

Hello!

I wanna ask you guys for help with this program. Here is my problem explanation: I want that user gives an input in the beginning of the program how big should tictactoe board would be. For example: input: 4 so board would be 4x4.

Code of the current problem is:

Lots of uncommentted code

Thanks for the help in advance.

Help with what? A problem statement and code does not explain the problem you are having.

And Greywolf333 is almost correct. While you do not need dynamic arrays, you really do need arrays.

I need an program, that ask user at the beginning how big board should be... If he inputs 4 then the board should be 4x4... This is only problem that haunts me :) Thanks for help.

Why does that haunt you? It will mean starting the code over, but you already know how to do a lot of it thanks to the code you posted.

Input n
Use a loop from 0 to n-1 to output your n rows.
Inside that, use another loop to output your n columns.
There's your board.

Get that part working.
